Be-it knownthat' I, HOWA D M. DUDLEY, citizenof the United States, and a resident of Philadelphia, inv the county of Philadelphia .and State of-Pennsylvania, have invented certain new and, useful Improvementsin Skein-Dyeing Machines, of which the following is a specification. V

My invention relates to skein dyeing machines and refers particularly to machines suitable for the dyeing of skeins by means ofaciroulating dye liquor.

:Oneobject of my invention is a device wl'iereby' skeins of textilefibers may be dyed evenly without manual manipulation.

Another object of my invention is a device in'which a dye liquor may bepassed in opposite directions through'fiberi skeins.

Another object of my invention is a device in which those portions of the skein which rest upon the supporting-bars are dyed evenly I with. other portions. 1 of the skein'.

Another object of my invention is a device in which the dye liquor is distributed evenly throughout the dyeing chambers. Another object of myinvention is a testing device whereby the condition ofthefiber in ithe dyeingchamber may be :determined without opening the dyeing chamber or disturbing or'i-njuring the skein' yarns therein. These and other objects. of my invention will be evident. upon a consideration of my specification, drawings and claims.

In;tl1e dyeing of'skein yarns it is'necessa'ry that the skeins bemoved" continuously through thedye liquor or thatthe dye'liquor be 'PHSSBCl-fCOIllZlIlllOUSlY through the skeins in" orderthat all portions of the'yarn receive equal treatment to produce'ev'en dyemgs. I

It is further necessary in the dyeing of I fibers of this character, to suspend or-support' each skein separately in order that the "fibers may not becometangles and thus interfere with the further operations." There is a tendency toward uneven dyeings atthose port-ions ofjthe' skein which rest'upon the supporting means, and which are usually not subjected to th'e same treatment as'those portions which are subjected to free Ytreatmentof the dye liquor. 1

""Mv' device overcomes all of the above and other difficulties and presents a method whereby uniform and even dyeing results Specification r LettersPatent; PatentedJune 4, 1918.

These universal joint 25. The pipe'24= isconnected with the pipe 26, which in turnis connected with the pump "57. The other side of'the pump =57=eis "connected-"With :the pipe 27,

whichis connected with the-pipe 28, carryzing thevalve 29 The pipe 28 is connected with a liquid supplytank (not shown).

The pipe 27 is also connected' withthe pipe 30 carrying the-valve 31', the pipe 30 benigconnected with the bottom of the reserve liquid tank 32. 'A pipe 33 carrying thevalve 70' connects the upper i portion' of' the dyeing chamber'with the top'of theireserve tank32. A pipe 71, carrying. the 'v'alve 72 iconnects ing :chamber by means of the .wing-nut clamp 37. Within the cover 36, and carried thereby, are a series of tubular "members 38.38.38 formedby the walls 39.39.39 and having downwardly divergent openings 40.40.40, formed by the end member's 41.41.41-abutting upon the upper face of theforaminous top 15. The tubular members extend outwardly into the tube or pipe 42,carrying the valve 43, and connected with the tube or pipe'44'connected with the universal joint 25. The joint 25 allows the cover 36 and the tubular members 38.38.38 to berevolved vertically intothe position shown in dotted lines in Fig. 1 and then revolved horizontally as shown in dotted lines in Fig. 3.

The skein holding means comprises a frame-work of the side members 84.84, connected together and the vertical members 46.46. Within the side member's 44.44 are a series of slots or openings 47.47 into which the round supporting bars 48.48.48. 48 may be introduced and from which they may be readily removed. A similar framework and supporting rods are introduced into the testing device 16. T

Theforaminous plates 10 and 15 consist of parallel and intersecting upwardly and downwardly extended converging members 50.50 between which are the supporting member's 51.51.

.gIn the modification shown in Fig. 8, the divergent openings 40.40.40 contain a series of divergent plates 52.52, for the further distribution of the'dye. liquor." C

; The-operation of the device is as follows: The skein carrying frame is removed from the dyeing chamber by means of the hoisting chain 53, the'rods 48.48.48.48- removed, the

skeins placed thereon'and the frame with the skeinslowered into the dyeing chamber until it rests-upon the lugs 54.54, as shown in Fig. '2, the cover 36 being in the position 36 of jFig-. 3. The foraminous top 15 is then placed within the dyeing chamber, the top 36 revolved into the position 36 of Fig. 1, then loweredinto the position 36 of skeins-is then placed in the testing device "ception of 29,23 and and the pump 57 is 16. The device is then-in position for the dyeing operation.

'All ofthe valves are closed with the exstarted. The dye-liquor passes downwardly through the pipe 28 into the pump 57 from through the foraminous plate 10, the dyeing chamber and the skeins contained therein, out through. the pipe 33, into the reserve tank 32. At the same time the dye liquor passes through the opening 18, the testing device with the skeins contained therein and out through the opening 17 thus treating the fiber in the testing device in the same'manner as the fiber in the dyeing chamber is treated. When sufficient dye liquor has been obtained fromthe dye liquor chamber (not shown) through the pipe 28, the valve 29' is closed and the valve 31 is opened. The dye liquor now passes upwardly through the dyeing chamber, outwardly through the pipe 33 into the reserve tank 32 and then through the pipes 30 and 27 into the pump 57, for continuous circulation. I

When the dye liquor has passed through the device in this direction for the required length of time, the valves .23 and 70 are closed and the valves 43 and 72 are opened. The dye liquor now passes through the pipes 26, 44, 42, the tubular members 38.38.38, the foraminous top 15, the dyeing chamber and the skeins contained therein, the pipes 71 and 33 into the'reserve tank 32 from which itreturns to the pump 57. through the pipes 30 and 27 for circulation. At the same time the liquor :passes through the opening 17, into and downwardly through the testing machine and the skeins contained therein and through the opening 18 into the bottom of thedyeing chamber. The skeins may be washed by admitting fresh water. through the pipe 34-into .the pump 57, after closing oiftheldye liquor. By having'the skeins 75. slightly longer than the. distance between. the bars 48.48.4848, they are clear of the .bars

4848 while the liquor is passing downwardly and clear of the bars48.48 when the liquor passes. upwardly fthusallowing even dyeings at those portions of the skeins.
